Anne Hathaway Celebrates Her Engagement with Her Fiancé – and Dog!

For Anne Hathaway, there’s no better place to show off a new diamond than on a walk through the park.

The actress, who recently got engaged to Adam Shulman, was wearing her engagement ring when she stepped out Sunday in Brooklyn’s Fort Greene Park with her new fiancé and her dog, a chocolate Lab named Esmeralda.

Shulman designed the ring in collaboration with Kwiat, whose diamonds are certified conflict-free. “Adam did work with us to design a ring that he knew Anne would love,” owner Greg Kwiat tells PEOPLE. “He had a very strong vision for what he knew Anne would love.”

The trio enjoyed a gorgeous fall day in a Brooklyn park, where they played fetch and sat together in the autumn leaves.

Hathaway and Shulman even indulged in some PDA, sharing kisses while Shulman kept a hand on Esmeralda’s leash.

The dog has been through thick and thin with the actress; Hathaway once shared Esmeralda with onetime boyfriend Raffaello Follieri, and the dog was staying at Follieri’s apartment when FBI agents arrived to arrest him.
